It's no secret I love planetaria. All you have to do is show up, take a seat, and they'll show you the stars! Or a video adventure that can explain black holes, or the planets, or why Saturn has rings. Millions of schoolchildren see planetarium shows every year, and I'm all for that.
And that's why I will (temporarily) bury the hatchet with PZ, who asked me to see if any Minnesotan astronomy enthusiasts out there would help rebuild and expand a planetarium in Minneapolis. They need to raise quite a bit of money, and it would be nice to see this new facility up and running.
Of course, I'm very much supportive of teaching more astronomy in Minnesota, especially if it means less time for biology. You have to have priorities.
